" 4 Clairns. (cl 105-218) The invention relates to trucks ior railwayrolling stock and moreparticuiarly to the support lug of the truck framefrom the truck axles. The main object of the invention is to support theframe from the truck by a' yielding device which will avoid directcontact between the axle boxes and the truck frame.-

In ordinary truck construction the frame has depending pedestalsembracing the journal boxes and limiting the relative movement of thejournal boxes and frame longitudinally and transversely'of the truck.The retardation and acceleration of the vehicle andthe play of thewheels transversely of the track set up numerous shocks which aretransmitted to the truck frame and from the latter to the car body,producing rough riding qualities which create wear in the parts anddiscomfort to the passenger when the truck is used in passenger carequipment.

The present invention contemplates the reduction or elimination of suchshocks by the use of a pedestalless type of frame and supporting theframe from the axle boxes by members mounted on the latter andyieldingly secured to the frame at points spaced from the axles.

In the accompanying drawings illustrating a selected embodiment of theinvention- Figure l is a top view ofone longitudinal half of afour-wheel truck.

Figure 2 is in part a side elevation and in part like recess adapted toreceive one of the upwardly projecting bosses t on' the adjacent journalbox arml.

Preferably each recess ls'provided with a rub-y her lining l3 fittingover the boss and a vertical bolt It extends through the top face of theboss,

lining ll, wall II, and a rubber-washer ii on top of wall II andissecured by a nut it, thus forming a pivotal connection between. theframe and the journal box member.

A coil spring i'l carried on seat 1 is" received "ins suitable cap it inthe adjacent portion of the frame wheel piece and preferably the cap isprovided with a pad I! of rubber-like material forming a cushion betweenthe frame and the spring. This padmay be faced with a-wear plate 20 toavoid abrasion of the rubber pad and provide more even distribution ofthe spring thrust thereto.

arm 8 maintains the assembly of these partaand a supplementary spring 22holds the bolt against play on the assembly but accommodates the 'com-,

a longitudinal vertical section through the truck and is taken on theline 2-2 of Figure 1.

Figure 3 is an end view of the truck structure shown inFigures land 2. v

Figures 4 and 5 are vertical transverse sections taken onthecorresponding section line of Figure 1. 1

The truck includes the usual wheels I and axles 2. Mounted uponeach-axle journal isa journal box I preferably having integral therewitharms 4 and 8 extending longitudinally of the truck,

arm 4 terminating in an upwardly projecting boss 8, preferably ofcirc'ular contour, and arm I terminating in an upwardly facing springseat I.

A truck frame extends, over both axles andincludes a wheel piece 8 ateach side of the truck in substantial vertical alignment with-journalbox arms 4 and I. The frame includes transoms i and end railsllextending transversely of the wheel pieces l at'opposite sides of thetruck.

Each wheel piece is shown as of box-shaped cross sectionandf its bottomwall ll is provided with annular ribs I! each cooperating with thebottom-walltoformadownwardlyfacingcuppression and expansion of framespring II. V

An anchor device 28 extends transversely of the truck between the outerend of each arm 5 and supporting a bracket 24 on the corresponding endrail is of v the truck frame. This anchor rod includes a bolt 2l, asubstantially shorter tube", opposins discs 2 between each end of tube26 and the adiacent end of bolt II, a nut 28, on the adjacent end of thebolt and pads 28 of rubber-like material between each disc 21 and theupright web III of bracket 24 or a corresponding web 3| of arm 5.

This construction permits relative movement in vertical directionsbetween the truck frame and the wheels and axles andjournal boxes andholds these parts against any substantial movement in transverse andlongitudinal directions, all such movements being cushionedto avoid thetransmission of shocks between the truck frame and the running gear.upon which it is mounted. Relative movement of thetruck frame andjournal box in horizontaldirections is positively limited by opposinglugs 32 and 33 on the frame and box respectively in the event of failureof any of the I connected 'll- Cross ties 34 extend between transoms iand seat coil springs ll which mount the'truck bolster it arranged tosupport the vehicle body (not shown) through any usual center plate asindicated at 31. Movement'of the bolster longitudinally of the truckrelative to the truck frame is yieldingly resisted by anchor devices iteach A bolt 2| through wheel piece 8, spring I! and connected at itsends to suitable brackets on the bolster and truck frame and constructedand functioning similarly to the anchor device a previously described.It will be understood that if desiredthe bolster may be arranged to movelaterally in the truck by providing the well known swing hangers andspring planks instead of supporting the bolster on springs mounted onthe frame cross ties 34 or any other bolster lateral motion arrangementmay be provided in combination with the new features coming within the 4The details of the construction are susceptible of numerousmodifications without departing from the spirit of the invention, andthe exclusive use of those modifications coming within the scope of theclaim is contemplated.

What is claimed is:

1. In a railway truck, a wheeled axle, a member supported on said axleand extending longitudinally of the truck in opposite directions fromsaid axle, a truck frame extending above said member, said member andframe having cooperating cup-like elements spaced in one direction fromsaid axle longitudinally of the truck and fitting each other with theircommon axis,

disposed vertically, and arranged so that the bottoms of said elementsprovide interengaging substantially flat circular horizontal bottoms touniformly transmit the vertical forces between them, said elementsforming a pivot between said memberand frame to accommodate theirrelative horizontal swinging movement, and means spaced in the oppositedirection from said axle tion havinga common vertical axis [in saidplane.

' above and in substantially the same longitudinal plane as said member,said wheel piece having a facing projection received insaid l'inedrecess,

ber supported on said axle and extending longitudinally of the truck inopposite directions from said axle, a truck frame including a wheelpiece downwardly facing cup-like.recess. spaced from said axle andprovidedwith a lining of rubberlike material, said member havingacorresponding upwardly facing projection received in said lined recess,'and a spring on said member for supporting said frame wheel piece, therecess and projection having a common vertical axisin said plane.

4. In a railway truck, a wheeled axle, a lever member supported on saidaxle and extending longitudinally of the truck in opposite directionsfrom said axle, a truck frame including a wheel piece member above andin substantially the same longitudinal plane as said lever member, oneof said members having a f vertlc'ally facing cup-like recess spacedfrom said axle and provided with a lining of rubberiike'inaterial, theother of said members having an oppositely and a spring on saidlevermember for supporting said wheel piece member, the. recess andprojecdescribed in claim 1 m
